Abstract:
A panel bending machine comprising: - a fixed lower table (3), - a movable upper table (4), - a plurality of blank holder tools (1,2) borne by the lower table (3) and by the upper table (4) and able to hold a piece of sheet metal (12) in a fixed position, and - a bending device (5) comprising a support structure (8) bearing two mutually opposite bending tools (6, 7) in fixed position with respect to each other. The upper table (4) is movable relative to the lower table (3) in a vertical plane, and a plurality of bending punches and dies (19, 20) are provided, susceptible to be mounted on the upper table and on the lower table (3, 4) to replace the blank holder tools (1, 2).
Abstract:
Bending press (10), comprising: - a stationary base structure (16, 18), - a fixed tool holder table (14), fixed relative to the base structure (16, 18), - a movable tool holder table (12), movable in a vertical plane relative to the fixed tool holder table (14), - at least two actuator devices (24) to command the movement of the movable tool holder table (12), positioned laterally relative to the movable tool holder table (12), and - at least one load application beam (34) whereon act said actuator devices (24), the load application beam (34) being arranged to apply the load to the movable tool holder table (12) in areas (36) positioned between said actuators (24).
